Background

An embedding box is a plastic box body commonly used in the biomedical field, and is generally made of plastic materials such as polyoxymethylene, and is generally used for embedding microorganisms, animals or plant cells in a solidifying medium to provide space support and chemical protection. In the field of medical pathology diagnosis and research, samples of materials to be embedded are usually derived from living tissue taken from a patient or laboratory animal, the embedding medium is usually paraffin, and researchers fill paraffin with chemically treated target samples in an embedding box. The embedding box comprises a main box body and a top cover. The main box body is an open-top box body stretched in a trapezoid cross section and is generally divided into a sample embedding area and a mark inclined area, wherein the sample embedding area is used for placing a bearing target sample, and the mark inclined area is used for adding marks to record relevant identification information. The embedding box top cover is used for closing the open top of the main box body and is provided with a buckle matched with the main box body.

In medical pathological diagnosis, information marks are needed for distinguishing, summarizing and storing management after different samples are embedded. Therefore, it is required to automatically print marking information on the cassette by using the cassette printing system, and the existing cassette printing system often adopts laser printing and inkjet printing. The laser printing is to send high-energy laser perpendicular to the surface of the box marking area by a laser printing head to burn at high temperature so as to form marks, and the embedded box base material is plastic such as polyoxymethylene, and the like, and the laser burning at high temperature is easy to generate toxic gas, pollute a laboratory and easily cause harm to human bodies; in the ink-jet printing, the special ink-jet ink is vertically sprayed on the surface of the marking area of the box by the ink-jet head, and then is irradiated and solidified by ultraviolet light, and the limited adhesive force of the marking area of the box to the ink-jet ink can limit the resolution of marking information, so the application range is limited.
